From what I understood zcash is one of the coins that ANT miner can not take advantage of because its algorithm: equihash depends on memory availability not the hashing speed. (I probably need to read more on this).
Now I had two gtx1080 equipped system started mining zcash from pool and see statistics below:
Both has 8GB DDR5X but only appears to be using 700MB for mining. Does that mean it is not utilizing its memory to its full potential and buying 11GB DDR5 edition will give no performance improvement? The quote below is taken from zcash web but not sure which memory it is referring to:
GPU memory 8GB
System mapped GPU memory (i.e. standard BAR address) usually 256MB for graphics
System main memory DDR4/3 etc interfaced to main processor.
And does anyone knows good technically sound crypto books and/or online resource on latest mining algorithms? I do have a very good book but it mostly covers older hashing and encryption algorithm i.e. SHA, RSA, but not Scrypto, Equihash. I dont know look through online crap articles on something written by non-technicals.
Thanks!

https://z.cash/blog/why-equihash"Equihash is a memory-oriented Proof-of-Work, which means how much mining you can do is mostly determined by how much RAM you have. We think it is unlikely that anyone will be able to build cost-effective custom hardware (ASICs) for mining in the foreseeable future.
